COUPLING FOR PIPE RAILINGS.

Application filed February 15, 1924:. Serial No. 693,137.

1 T0 aZZ whom it may concern:

Be it known that I, LOUIS G. HALLER, a

citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Coupling for Pipe Railings, of which the following is a specification.

This invention relates to couplings for pipe rallings.

The object is to provide coupling means for connecting the tubular rails to the tubular POSlZSOf this class of railings and to provide a positive locking together of the parts that will prevent accidental separation of the same under the severest strains to which such railings are subjected.

Another object is to provide locking means, which, when driven into position for holding the parts together, will form a seat for itself in the tubular post or in the tubular railing, either near the ends or intermediately of the same, thus positively avoiding any lost motion or movement of the parts, as when such seats are previously formed.

A further object is to provide locking means for such couplings which, when fully driven into position, are completely hidden from view and offer no projections to catch on the clothes or injure the hands.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the ac companying drawing forming a art of this specification; it being understoo that while the drawing shows a practical form of the invention, the latter is not to be confined to strict conformity with the showing there of, but may be changed or modified, so long as such changes or modifications mark no material departure from the salient features of the invention, as specifically pointed out in the appended claims.

In the drawing, in which similar reference characters designate corresponding parts throughout the several figures;

Figure 1 is a vertical sectional view through a coupling for connecting the end of an intermediate rail to an end post of a tubular railing.

Figure 2 is a vertical section through the sleeve or socket of the coupling, the railing pipes being omitted.

Figure 3 is a horizontal sectional view through the device taken on the line 33 "of Figure 1, and showing the locking pin being driven into position. a

Figure 41- is a similar view, the locking pin'being shown in locked position.

Figure 5 is a detail elevation of a portion of one ofthe railing pipes and showing the 7 seat formedtherein by the locking pin.

Figure 6 is a detail perspective view of the locking pin,

In the drawing there is illustrated a tubular sleeve 1 which preferably, for ornamental purposes, has its central portion formed into globe shape, though this is not necessary, as the sides may be straight or parallel, as will be readily seen.

The sleeve 1 is formed of suitable cast metal, and in the particular showing in the drawing consists of what is known as a l -coupling having three sockets 2 formed therein, though this is only one of many forms of couplings in which the invention may be used, as it may be applied to Ts, elbows, crosses, Y-shaped couplings or floor flanges, or in any other similar place where it is' desired to secure a tube or red rail or bar into a sleeve or socket.

The coupling shown would properly be used for securing the end of an intermediate rail 3 to an upright post 4 such as would occur at the end of a fence or railing or at a gate, the rail 3 and the post 4; consistlng of metal tubing, and the latter being shown as comprising two sections though the same may be continued on through the sleeve las one continuous piece, in certain cases. I

The sleeve 1 is provided at one side between the vertical alined sockets and the horizontal socket 2 with webs 5 formed integrally therewith and preferably quadrantshaped in side view, the said webs being centrally located and considerably narrower than the diameters of the sockets.

Transverse bores or passageways 6 are formed through the webs 5 adjacent to the bores or" the sockets 2, and said bores or passageways are provided with longitudinal extensions 7 along their inner sides, said extensions cutting through the inner wall of the socket at the central portion of the holes or passagewaysand thus communicating with the same. The extensions 7, as shown in Figure l of the drawing, are V-shaped in cross section and the communicating opening 8 (see Figure 2) is elongated and arranged transversely of the bore of the socket.
